Product details
The CPI LRC1 is a 1:1 redundant LNA system from CPI's LRC-1000 Series for C-Band earth stations. It protects one receive chain: an online LNA and a hot spare share an outdoor switch plate at the antenna hub, and the indoor controller switches to the spare automatically if the online LNA fails.
The plate carries CPI LC-4000 Series LNAs (30, 35, 40 or 45 K) on a CPR-229G waveguide input, with options for Tx reject filters, -40 dB input crossguide couplers, -20 dB output couplers and an offline I/O port. The 1RU controller has dual power supplies and SNMP over Ethernet.
Order it as LRC1XXX-XXXXXXX; Digisat completes the order code from your band, LNA and option choices. The LRC-1000 Series comes in 2 listed models; compare them on the series page.
